Title: Improvements in, or relating to, furnaces
Inventor: GREENHALGH HAROLD
IPC: F27B9/24
Filed: 1955-11-04
Abstract: 854,359. Electric induction furnaces. SALEM ENGINEERING CO. Ltd. Feb. 4, 1957 [Nov. 4, 1955], No. 31521/55. Class 39(3). [Also in Group XII] A continuous furnace for heat treating metal billets 6 comprises separate sections 2 of refractory cement 3 enclosing an induction coil 5 and lined with a refractory tube 4, each end of each section being formed with a transverse recess, so that, when the sections are assembled end to end, openings 7 are formed at each junction. The induction coils are so rated as to divide the tunnel into a slow preheating zone, a rapid treating zone, and a soaking zone. At the leading end of each section is a work support 8 (not shown) comprising overlapping, superimposed wedges 9 and 10, Fig. 4, the latter being adjusted by a manually rotatable shaft 11 to vary the support height. Alternatively the wedges may be adjustably arranged side by side transversely of the corresponding opening 7. A beam structure 15 extending below the furnace carries at each opening 7 brackets 14 supporting a roller 12, and is supported by pivoted arms 20 connected at each end to pvioted levers 21, 22. Some of the levers 22 are bell cranks connected to a rod 24, reciprocated from a crank 26 to move the rollers periodically through the openings 7 raising the billets off the supports 8. The rollers may be positively driven through sprocket gearing 18 to move the billets, or they may be idling rollers, movement of the billets being imparted by an incoming billet driven by a ram 19. The latter is timed to move a billet from a loading station 27 into the furnace as the rollers reach the extreme uppermost position, and synchronised doors may be fitted at the tunnel ends. In a modification, Fig. 5 (not shown), the rollers 12 are replaced by refractory blocks suspended on pivoted arms and given continuous alternate vertical and horizontal movements after the manner of a walking- beam conveyer by a system of pivoted levers with horizontal rods mounted eccentrically at one end of the furnace on gear wheels disposed on opposite sides of a driven gear wheel.

Title: Improvements in or relating to moulds for metal casting
Inventor: SHAW NOEL
IPC: B22C1/08
Filed: 1956-10-17
Abstract: Refractory moulds for metal casting (see Group XXII] are produced by pouring around a pattern a slurry of alumina, calcium sulphate and an aqueous solution of an alkali metal silicate of specific gravity 1,05 to 1,2 and, when the slurry is set by gelling, removing the pattern without previous drying and placing the product in an oven until it becomes rigid.  The product may be a mould or part of a mould.  The pieces of a composite mould so produced have their meeting faces treated with hexamine solution and the joints treated, after assembly, with a mixture of casting solution and alumina, and the mould is then re-heated. Preferably, precipitated alumina granulated by ignition is used, the silicate is potassium silicate and the calcium sulphate is partially burnt gypsum.  For some purposes sillimanite and sodium silicate may be substituted for alumina and potassium silicate respectively.  The character of the product, and the gelling time, are governed by the proportion of gyspum and the specific gravity of the solution, and an example is given of a satisfactory slurry which has a gelling time of one and a half minutes; suitable oven temperatures are also mentioned.

Title: Improvements in electrical communication systems
IPC: H04Q11/04
Filed: 1947-12-01
Abstract: 657,492. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Dec. 1, 1947, No. 31691. Convention date, Oct. 5, 1946. [Class 40 (iv)] [Also in Group XL (c)] In a pulse gating arrangement for appropriating idle circuits in a distributer multiplex exchange system, the first channel pulse is directed over a series circuit to the first idle circuit which thereafter generates gating pulses which (1) enable it to accept subsequent pulses belonging to that channel, (2) open the series circuit at these instants to prevent intrusion of the pulses on further circuits, and (3) close the series circuits at other times to direct first pulses originating from other channels to the next idle circuit. As shown in Fig. 3, a first channel pulse is admitted by valve Vg (see Group XL (c)) and valve V<SP>2</SP>to the circuit I, amplified by V<SP>3</SP> and fed to a long time constant circuit Cg, Rg to cause valve V' to produce a long pulse A<SP>2</SP> which cuts off V<SP>2</SP> during the period between successive pulses belonging to the calling channel to prevent intrusion of first pulses of other channels. Pulse A<SP>2</SP> amplified by V<SP>7</SP> also opens the gate V<SP>1</SP> to transmit these latter pulses to subsequent circuits II. The trailing edge of A<SP>2</SP> is also differentiated to provide a pulse C, which closes the gate Vg to subsequent pulses of the calling channel, and a pulse B which opens the gate V<SP>5</SP> to admit these subsequent pulses to the circuit I where they are fed to valve V<SP>3</SP> to maintain the pulse circulation therein and so maintain the circuit in the engaged condition. A modification, Fig. 3 (not shown), uses gate circuits in which pulses are prevented from appearing in the appropriate circuits by shunting them to earth (see Group XL (c)). An arrangement using electromagnetic relays, Fig. 1 (not shown), is also described.

Title: Solid electrolyte electrochemical timer
Inventor: GILES STUART
IPC: H01H43/32
Filed: 1969-06-24
Abstract: 1,261,090. Electrolytic meters. NORTH AMERICAN ROCKWELL CORP. June 24, 1969 [June 27, 1968], No.31944/69. Heading G1Q. In an electro-chemical timer of the type in which during operation plateable material migrates from a first electrode including a source layer of the plateable material through a solid electrolyte layer to a second electrode layer during a set mode and in the reverse direction during a timing mode, the source, electrolyte and second electrode layers are maintained during operation under a predetermined compressive stress. The arrangement is such that a substantially constant total dimension of source, electrolyte and second electrode layer is maintained in the direction of stress, despite migration of plateable material, thus avoiding the risk of internal damage. The plateable material is provided in the form of a thin silver layer 52 between the first electrode 16 and the solid electrolyte 20. The silver may be plated on the first electrode or may be a separate foil. The action during a set operation is such that the thickness of silver deposited on the second electrode 26 is the same as that of the silver lost from the layer 52, while in a timing operation the thickness lost from the electrode 26 corresponds to that built up on the layer 52. The prestressed condition is maintained by the inwardly swaged lip edge 28 of the container 30.

Title: Phase-shifting circuits
Inventor: NUSSBAUMER HENRI JEAN
IPC: H03H17/08
Filed: 1969-06-25
Abstract: 1,254,223. Active filters; phase lock circuits. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1969 [5 July, 1968], No. 31971/69. Heading H3A and H3U. A phase shifter comprising capacitors C1 ... C4 connected to an input 1 via respective input switches S1 ... S4 and to an output 1<SP>11</SP> via respective output switches S5 ... S8 is characterized by the provision of means for varying the relative operating time of corresponding input and output switches to vary the phase shift. A second set of output switches operated at different phases from switches S5 ... S8 may be added to give a different phase output, Fig. 9c (not shown). The circuit may be used in a data transmission system, for locking the phases of the received modulated carrier and the data rate to those of locally generated carrier and clock signals respectively. The carrier lock circuit, Fig. 3, comprises a phase shifter SF2 of the type described fed with the received carrier signal to provide a first input to a phase comparator " LOGIC." The local signal provides a second reference input p and the resulting error output from the comparator is applied to an AND gate together with the output from an oscillator OSC2, to adjust the timing of the output switches of the phase shifter relative to the input switches. The output from the oscillator is fed to a first divider path d3, d4 to operate the input switches, and a second similar divider path is included between the AND gate and the output switches. The dividers may comprise a chain of binary circuits with the necessary outputs taken from different points along the chain. Fig. 6 (not shown). In this Figure, the comparator " LOGIC " is shown to produce further timing pulses which vary the timing of output pulses from divider d5, d6.  The data lock circuit, Fig. 9a (not shown), uses a similar control circuit in which a phase shifter (SF4) is fed with data signals and is controlled by an oscillator (OSC) via a divider (d<SP>11</SP>). A modification, Fig. 9b (not shown), employs the phase shifter of Fig. 9c (not shown), to give phase displaced outputs.

Abstract: 366,085. Indicating apparatus on motor vehicles. SPORT SOC. ANON., 12A, Rue de la Plaenke, Bienne, Switzerland. Oct. 24, 1930, No. 32011. Convention date, Oct. 26, 1929. [Class 79(iii).] An electromagnetic cut-out for use in motor vehicles in an arrangement for indicating the state of charge of the battery and the failure of the rear lamp is provided with a spring- mounted armature adapted to be attracted to an electromagnet formed with an eccentric flange of magnetic material so that by rotation of the electromagnet and core the air gap between the flange and the free end of the armature is varied to adjust the relay for operation at different voltages. As shown in Figs. 1 and 2 the electromagnet 3 on the core 2 is provided at its lower end with an eccentrically mounted disc 4 of magnetic material. The armature 9 is carried by a blade spring 8 secured to an L-shaped magnetic strip 7 through which a reduced portion of the electromagnet core 2 passes and is secured on the outer side of the casing by a nut 6. By slackening off the nut 6 and rotating the core by means of a screwdriver slot formed therein the gap X between the plate 4 and the armature 9 is varied, so varying the voltage at which the armature is attracted. In a modified form, Fig. 4, the core may carry a pointer 23 moving over a calibrated scale 24 the core being held in its adjusted position by a clamping screw 25 bearing on a slotted extension 24 of the pointer. The relay is mounted in a casing with an indicating lamp 13 and when the battery voltage is below a predetermined minimum the indicating lamp circuit is completed in series with the vehicle rear lamp at a back-contact 10. The rear lamp is, however, shunted by a resistance so that if its filament breaks this resistance is placed in circuit with the coil 3 so causing the armature to be released and the indicating lamp to be lighted.
